AN5870K
Wide bandwidth analog switch IC
s Overview
The AN5870K is a wide bandwidth analog switch IC of 300 MHz operation. It is usable for RGB signal and horizontal/vertical synchronizing signals, and it has a built-in 75 Ω driver for video signal. In addition, it has also realized a high speed operation by the adoption of CMOS process for its sync. signal processing circuit. It is usable in a broad range from a popular type monitor to a high definition monitor.
